Arsenal legend Emmanuel Petit claims Mesut Ozil has 'been a ghost for two years' at the Emirates after losing his desire to be a world class football star.

According to a UK Daily Mail report citing Daily Mirror, Ozil, who penned a new £350,000-a-week contract at the Emirates Stadium in January, has continued to struggle under Arsenal boss Unai Emery, and was substituted at half-time during the draw at Brighton.

And Petit, who featured in 116 games for Arsenal during his playing days winning the Double back in 1998, has now criticized Ozil for his below-the-par performance.

“Mesut Ozil was taken off at half-time. I'm a big fan of his, but he has been a ghost for two years,” the club icon Petit told the Daily Mirror.

“Where is the Ozil who was one of the best players around, making so many assists and goals? I think he has lost his desire on the pitch, it's not there anymore.”

After 22 games unbeaten run in all competition between August and mid-December Arsenal lost 3-2 at Southampton and then crashed out of the Carabao Cup with a 2-0 home loss to north London rivals Tottenham.
